While angular cheilitis may be caused by vitamin B and iron deficiencies, bacterial infections, and the chronic habit of licking the corners of the mouth, the majority of cases are fungal in nature. The organism Candida albicans is most associated with oral fungal infections. Angular cheilitis is treated with a topical antifungal medication combined with a topical steroid in a prescription ointment known as Mycolog II (nystatin with triamcinolone).
